After he got his fins on, we swam out past the swim buoy and descended, then slowly headed East towards the Jacks. It took us about an hour to get to the 3-tiered reef, where I checked Han's gas. He was down to 1000 psi. We turned the dive and headed back to the beach, but we were close to the Jacks.
Han ran out of air and surfaced just after the swim buoy. We swam in on the surface, a little North of Tower 2.
Water temperature was 76 degrees; Dive Time was 78 minutes; actual consumption at an average depth of 17 feet was 25.76 psi/minute; SAC rate was 17 psi/minute; and RMV was 0.44 ft3/minute.
